The Partnach Gorge (German: Partnachklamm) is a deep gorge that has been incised by a mountain stream, the Partnach, in the Reintal valley near the south German town of Garmisch-Partenkirchen. The gorge is 702 metres long and, in places, over 80 metres deep. It was designated a natural monument in 1912. Source: http://en.wikipedia.org/wiki/Partnach_Gorge
